Many Chinese makers share the same design but different brands, check out the pictures. Cortina Model, Please see attached PDF, also visit https://youtu.be/yfsslPiN3Ao. Characteristics: This adapter model is designed to be 3D printed on deposition machines and allows users to use the best filtration membrane they have access to, preventing the mask from being unusable due to a lack of specialized filters. The device consists of two parts: the adapter that connects to the mask where the snorkel would originally connect, and the grill that traps and seals the filter membrane against the adapter. The filter is a cutout of any available filter membrane such as N95 masks, P100 filters, cloth, coffee filters, or HEPA vacuum cleaner bags without fiberglass. Advantages: • The device can be easily manufactured on 3D deposition machines. • By allowing various filter membranes to be used, it prevents the mask from becoming obsolete. When resources are scarce, it allows protection even if it's not the ideal material. • Disposable N95 masks must be discarded because they lose their shape and stop sealing against the face due to moisture exposure and constant user manipulation. With this device, the filter material of the mask lasts much longer since it is less exposed to moisture and its structure is permanently maintained between the adapter and the grill. • The device can be easily cleaned with soap and water (without the filter membrane). • The device is more compact, preventing it from extending far beyond the head and exposing it to shocks. • A single filter membrane resource can be transformed into several by cutting it into 2 or more pieces. For example, a single N95 mask can be cut into multiple filter membranes. • The device can be quickly redesigned to fit different snorkel mask models. • The device allows you to cover the grill with your hand to perform the face seal test with the mask when inhaling and exhaling with the grill locked.
